Banned Books...Not Sure Where I Stand

I am actually not sure where I stand on this Issue. While I can see why some books are banned, I'm not sure why people should not be able to read what they please. I agree with some books being unavailable to immature audiences, I believe that people who can handle, understand, and are mature enough for the books, should be able to read them. I think that books that portray hatred towards other should be banned, but books banned for vulgarity and and sexual content should just be kept for mature audiences only. I can point out that a lot of the books were banned back in the early to mid 1900's, which was a MUCH more conservative times, so some of the banned books that were banned for language or content are not as bad as banned books that are banned today. For example, Annie on My Mind is banned because it is about to teenage girls who fall in love with each other and struggle with coming out, and it is banned, simply becuase of homosexual content. I believe that is wrong. But, with a book like Lolita, About child rape, I think that should be banned.
